2.66 Ct. Blue Sapphire from Thailand

This exceptional, transparent 2.66 carat oval blue sapphire is a rare find, an elegant statement of refined taste offered exclusively by The Natural Sapphire Company. Measuring 10.20 x 7.66 x 3.84 millimeters, the gem presents a graceful oval silhouette that flatters any setting, from a classic solitaire to a bespoke halo design. Cut to a mixed brilliant pattern, the facets have been arranged to balance deep, velvety saturation with lively internal reflection, allowing the intense blue color to reveal itself in movement without losing its depth. Evaluated at eye level and graded as very slightly included, the clarity affirms the gem as transparent and visually clean, while the excellent polish enhances surface luster and tactile smoothness. Originating from Thailand and heat treated to bring out its best qualities, this sapphire embodies the storied heritage of Southeast Asian mines and artisans, and because stones of this calibre do not appear often, owning it places you among a small circle of collectors and connoisseurs who value true natural beauty and provenance.

When selecting a gemstone for daily wear or an investment piece, durability is paramount, and this sapphire delivers with confidence, scoring nine on the Mohs hardness scale. To put that in perspective, diamond rates ten on the same scale, and common jewelry gemstones such as quartz rate seven, meaning this sapphire resists scratches from almost all other materials you encounter in everyday life, and it will maintain its polish and crisp facet edges through years of wear. The mixed brilliant cut further contributes to resilience, as the facet arrangement reduces the visibility of minor surface wear and distributes light in a way that masks tiny abrasions, so the stone maintains its aesthetic appeal with minimal maintenance. The heat treatment this sapphire has undergone is a widely accepted and stable enhancement that optimizes color while preserving structural integrity, so you can expect consistent performance from a gem that is both visually arresting and practically durable for rings, pendants, or bespoke pieces designed for frequent use.

As custodians of fine sapphires, The Natural Sapphire Company invites you to own this singular gem as part of a private, limited offering that celebrates rarity and personal connection. We offer tailored consultations to advise on mounting styles that accentuate the oval proportions, to design custom jewelry that frames the intense blue color, and to ensure the setting protects the girdle and pavilion while maximizing light return. Each purchase is accompanied by detailed provenance information and a full assessment of the gem characteristics, so you will have confidence in the quality, treatment disclosure, and origin. For the discerning collector or the person seeking a meaningful symbol of commitment, this Thai sapphire stands as a tasteful and enduring choice, an heirloom quality stone that promises to be admired for generations, and we would be honored to guide you through ownership, bespoke design, and secure delivery to ensure this rare treasure becomes a signature piece in your collection.
